I 'l he invention relates towimprovements in soldering i'furnaoesyand more-)particularlyto such furnaces "of theportable type.

The; primary 1 object ofwmy invention -is-- to 5 provide a new-mud improved: soldering rim-- nace which is ada ted to formiipart-aofl-a complete soldering *itor outfit-particularly suitable :for *USBElIIJtAhG 'hOXDO or on anv utomobile, and which i more ispeeifimlly' -i's ip'rovided with: 'compafiments r adapted: to "receive the essential soldering-accessories. t

Another object is: to provide-novel means forextinguishingthe flame and enolosingthe burners to prevent leakagerand:-eveporation.

A further; object fiSitOi iprovitle a portable soldering furnace which usvsimpleandrcompact in conruction inexpensiveand: easy to manufacture, and shaving i an "exceptionally Other objects and aidmtages willwbecome apparent as the description proceeds.

While my invention" is susceptible; of various modifications and alternative constructions, I have shown in the drawings and will herein describe in detail the preferred embodiment, but it is to be understood that 5 I do not thereby intend to limit the invention to the particular form disclosed but aim in the appended claims to cover all modifications and alternative constructions falling within the spirit and scope of the invention. Referring to the exemplary embodiment illustrated in the drawings, 10 re resents the body of the furnace which pre erably consists of a rectangular box open at the top and at one end, and 11 designates a suitable cover adapted to completely close the box. In the cover 11, as shown, the edges are bent down to provide a flange 12 adapted to fit over the upper edges of the box 10, and one end is formed with a depending plate 13 for closing the open end of said box. The plate 13, when the cover 11 is in position, fits in- F ig. 2 is a longitudinal section taken along side of -two vertical flanges 114: nformed .:-by bending-the front edges of the side wallsof thevbbxddinwardly. v Q

The-bottom of the box 10' is closed by a hollow rectangular, base 15 which is adapted to serve as a reservoir for the, fuel, such as denaturedalcohoh In the present instance, the base 15 isconstructed of a lower section lfi torwhiehwthe wallsof the box 10are soldered, ta-nd an upper sectionl'? telescoping into the-:lowerisection andsoldered thereto to obtaima tight-joint. -A flanged filling opening 18- is formed inthe front end of the sec: tion 17 and-is normally :closed by a' oork 11-9 Mounted on'the base 15 :within "the closed end aof the box =10 "is r-avburnerz whicln preferably comprises a tHbBfQOwSBCHIYGClJ-llO the section '17, and asuitable wick -21-cxtending through the tube .into the incl. J/Vhem the furnace :is not fin use, a it-ubular cap 22* is adapted to telescope'with "the tubeflO to' close the latter. The ea-p.22 acts as :a flame extinis formed with a rectangular opening 26 directly over the burner tube 20 to expose the element to be heated to the flame. This element is herein shown as a soldering iron having a head 27 and atelescoping handle 28. The sides 29 of the opening 26 are bent upwardly and inwardly to form a burner hood which serves to protect the flame and to direct and confine it to the head 27. When not in use, the soldering iron can be telescoped and positioned at one side of the hood as shown in Figs. 2 and 3.

It will be evident that I have provided a handy soldering furnace which can be, ad vantageously used in the home,'the automobile, and other places for light jobs, such as soldering electrical connections and radio equipment, or repairing utensils and the like. The furnace is small and compact, and can be carried with the necessary soldering accessories in the pocket or tool kit to be set up and used where needed, thereby providing an elficient self contained soldering outfit.

I claim as my invention:

1. A soldering furnace having, in combination, a. body open at the top and front, and closedat the bottom by an integral fuel container, a filling opening in the front end of said container, :1 wick burner in the form of a tube on the-other end of said container, a combined tool holder and burner hood movably mounted in saidbody over said container, a flame extinguisher adapted to telescope with said burner, and a cover having a depending plate at its front end, said cover beingadapted to close said body.

2. i soldering furnace having, in combination, a body closed at the bottom by an integral fuel container, a burner on one end of said container, and a tool holder removably mounted in said body, said tool holder consisting of a piece of metal having bent down sides constituting legs and being formed with a hole directly over said burner, and flanges on two opposite sides ofsaid hole extending upwardly and toward each other toconstitute a hood.

3. A soldering furnace having, in combination, a body in the form of a box, a fuel container forming the bottom of said box, a burner on said container, a removable tool holder and burner hood in said box, and

means for closing said box.

4. A soldering furnace having, in combination, a rectangular body open at the top and front and closed at the bottom by a fuel container, a cover for closing said'top and front, a burner on said fuel reservoir,

and a hood having inclined sides over said burner.

5. A soldering furnace having, in combination a rectangular box, a fuel container in the bottom of said box, a filling opening in one end of said container, a burner on the other end of said container, a combined hood and tool support removably mounted in said box on said container with the hood positioned over said burner, and a removable cover for closing said box.

6. A soldering furnace comprising, in combination, a box, a fuel reservoir in the bottom of said box, a tube burner on one end of said reservoir provided with a wick, and a tubular cap telescoping over said burner tube, said cap serving as a fire extinguisher and to prevent leakage and evaporation of fuel.

7. A soldering furnace comprising, in combination, a box having a fuel reservoir in the bottom thereof, a burner on said fuel reservoir, :1 tool holder removably mounted in said box, said holder defining a compartment for receiving various soldering accessories, a hood over said burner, and a cover for closing said box.

8. A soldering furnace having, in combination, a box open at the front and top, and containing a fuel reservoir at the bottom thereof, a filling opening at the front end of said reservoir, a. burner on the other end of said reservoir, a combined tool holder and hood in said box with the hood positioned over said burner, said last element defining a compartment over said reservoir for receiving various soldering accessories and constituting a shaft for supporting a soldering iron when not, in use, and a cover for completely closing said box.

.In testimony whereof, I have hereunto allixed my signature.
